int std::moneypunct< CharT, Intl >::frac_digits | ( |  | ) | const`[inline]`

| Return number of digits in fraction. This function returns the exact number of digits that make up the fractional part of a money amount. It does so by returning returning moneypunct<char_type>::do_frac_digits(). The fractional part of a money amount is optional. But if it is present, there must be frac_digits() digits. Returns: Number of digits in amount fraction. Definition at line 3713 of file locale_facets.h. References std::moneypunct< CharT, Intl >::do_frac_digits().

template<typename CharT, bool Intl>
string std::moneypunct< CharT, Intl >::grouping | ( |  | ) | const`[inline]`

| Return grouping specification. This function returns a string representing groupings for the integer part of an amount. Groupings indicate where thousands separators should be inserted. Each char in the return string is interpret as an integer rather than a character. These numbers represent the number of digits in a group. The first char in the string represents the number of digits in the least significant group. If a char is negative, it indicates an unlimited number of digits for the group. If more chars from the string are required to group a number, the last char is used repeatedly. For example, if the grouping() returns "\003\002" and is applied to the number 123456789, this corresponds to 12,34,56,789. Note that if the string was "32", this would put more than 50 digits into the least significant group if the character set is ASCII. The string is returned by calling moneypunct<char_type>::do_grouping(). Returns: string representing grouping specification. Definition at line 3650 of file locale_facets.h. References std::moneypunct< CharT, Intl >::do_grouping().

template<typename CharT, bool Intl>
pattern std::moneypunct< CharT, Intl >::neg_format | ( |  | ) | const`[inline]`

| Return pattern for money values. This function returns a pattern describing the formatting of a positive or negative valued money amount. It does so by returning returning moneypunct<char_type>::do_pos_format() or moneypunct<char_type>::do_neg_format(). The pattern has 4 fields describing the ordering of symbol, sign, value, and none or space. There must be one of each in the pattern. The none and space enums may not appear in the first field and space may not appear in the final field. The parts of a money string must appear in the order indicated by the fields of the pattern. The symbol field indicates that the value of curr_symbol() may be present. The sign field indicates that the value of positive_sign() or negative_sign() must be present. The value field indicates that the absolute value of the money amount is present. none indicates 0 or more whitespace characters, except at the end, where it permits no whitespace. space indicates that 1 or more whitespace characters must be present. For example, for the US locale and pos_format() pattern {symbol,sign,value,none}, curr_symbol() == '$' positive_sign() == '+', and value 10.01, and options set to force the symbol, the corresponding string is "$+10.01". Returns: Pattern for money values. Definition at line 3752 of file locale_facets.h. References std::moneypunct< CharT, Intl >::do_neg_format().

template<typename CharT, bool Intl>
string_type std::moneypunct< CharT, Intl >::negative_sign | ( |  | ) | const`[inline]`

| Return negative sign string. This function returns a string_type to use as a sign for negative amounts. It does so by returning returning moneypunct<char_type>::do_negative_sign(). If the return value contains more than one character, the first character appears in the position indicated by neg_format() and the remainder appear at the end of the formatted string. Returns: string_type representing a negative sign. Definition at line 3697 of file locale_facets.h. References std::moneypunct< CharT, Intl >::do_negative_sign().

template<typename CharT, bool Intl>
pattern std::moneypunct< CharT, Intl >::pos_format | ( |  | ) | const`[inline]`

| Return pattern for money values. This function returns a pattern describing the formatting of a positive or negative valued money amount. It does so by returning returning moneypunct<char_type>::do_pos_format() or moneypunct<char_type>::do_neg_format(). The pattern has 4 fields describing the ordering of symbol, sign, value, and none or space. There must be one of each in the pattern. The none and space enums may not appear in the first field and space may not appear in the final field. The parts of a money string must appear in the order indicated by the fields of the pattern. The symbol field indicates that the value of curr_symbol() may be present. The sign field indicates that the value of positive_sign() or negative_sign() must be present. The value field indicates that the absolute value of the money amount is present. none indicates 0 or more whitespace characters, except at the end, where it permits no whitespace. space indicates that 1 or more whitespace characters must be present.

template<typename CharT, bool Intl>
string_type std::moneypunct< CharT, Intl >::positive_sign | ( |  | ) | const`[inline]`

| Return positive sign string. This function returns a string_type to use as a sign for positive amounts. It does so by returning returning moneypunct<char_type>::do_positive_sign(). If the return value contains more than one character, the first character appears in the position indicated by pos_format() and the remainder appear at the end of the formatted string. Returns: string_type representing a positive sign. Definition at line 3680 of file locale_facets.h. References std::moneypunct< CharT, Intl >::do_positive_sign().

template<typename CharT, bool Intl>
char_type std::moneypunct< CharT, Intl >::thousands_sep | ( |  | ) | const`[inline]`

| Return thousands separator character. This function returns a char_type to use as a thousands separator. It does so by returning returning moneypunct<char_type>::do_thousands_sep().
